I have Quadlock connector with full cabling as well, but as I was using this set with MS8, it might require some soldering or tweaking. Price TBD.

I was using DB501 as front door speakers, DXi400 as rear door ones and center dash. It's very tight fit to dash and might require some modification (I had base audio (6speakers, no amp), so I needed to cut speaker hole to dash).

Hifonics was powering front and center, while Vibe did rears and underseats. All were synced by MS8 (not on sale).

The set is primarily for pickup in Belgium (Brussels), but I may post in EU on buyers cost.
